随着普光气田的探测发现,国家加大对湿气田的探索开发。湿气管道内存在三相流动时,界面模型的选取对管线压降与管流平均持液率计算准确性具有一定影响。根据各界面模型对实验数据的计算效果,分析各界面模型的适用条件,为建立完善的湿气管道水力计算模型提供理论依据。 With the discovery of the Puguang Gas Field, the state has stepped up exploration and development of wet gas fields. When the three-phase flow exists in the wet gas pipeline, the selection of the interface model has certain influence on the calculation accuracy of the pipeline pressure drop and the average liquid holdup of the pipe flow. According to the computational effect of each interface model on the experimental data, the applicable conditions of each interface model are analyzed, which provides a theoretical basis for establishing a perfect hydraulic pipeline hydraulic calculation model.
